CONDENSER.

Application Vtiled April 24, 1917. SerialNo. 164,106.

Be it known that I, ARTHUR K.' WHITE- LAw, a citizen of the UnitedStates, and a resident of Woodriver, in the county of Madison and Stateof Illinois, have invented a new and Improved Condenser, of which fcient apparatus which will be economical.y

and increase the yield and the quality of the product.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combina.- tion and arrangement of parts as hereinfully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar.characters of reference indicate corresponding parts in both views.

Figure 1 is a vertical section of' my condenser shown in its relation tothe still and submerged surface condenser; and

Fig. 2 is a horizontal cross section.

My still is particularly designed for the Burton process of distillingcrude petroleum under pressure, but it is also adaptable to othermethods of refining petroleum, whether under pressure or otherwise. Theapparatus consists of concentric cylinders 3 and 4 mounted vertically.The heads 5 and 6 respectively of the outer cylinder 4 serve also asheads for the inner cylinder 3. The annular space formed between thecylinders is the preheating chamber 7 for the crude oil or distillatefed thereinto through a conduit 8, preferably located near the lowerendof the outer cylinder.

The inner cylinder 3 has a conduit 9 near the top thereof constitutingan overiow from said chamber 7 into the inner cylinder. It discharges onto a plate 10 carried by a rod 11 mounted concentrically within theinner cylinder 3 from a spider 12 provided .near the lower end of saidinner cylinder. The said rod 11 carries a series of said plates 10through its length. The said plates are alternated bycentrally-apertured plates 18 secured at the margin to the cylindricalsurface of the inner cylinder 3. In consequence, the liquid delivered bythe conduit 9 to the first plate drips on to the centrallyaperturedplate underlying it, from where the liquid falls on to the next pl'ate10 therebelow, etc., until it reaches the lower head 6, Whereat a'conduit 14 is provided which connects the inner cylinder with a still15.

The conduit 14 serves as a vapor conduit from the'still to thecondenser, and also as a feed to the still for the non-vaporized liquidportions remaining from the liquid whichoverflows into the innercylinder, and for the undesirable and heavy fractions carried off by thevapors from the still and interrupted or recondensed by the liquid whichoveriows into the inner cylinder from the chamber 7. .x

The upper head 5 of the cylinders is connected by a conduit 16 to asubmerged surface condenser 17 wherein the vapors from the innercylinders are condensed. A direct feed conduit 17 is provided 'for theinner cylinder 3V whereby oil or distillate can be fed directly intosaid inner cylinder without a How through the preheating chamber. Thechamber 7 is provided with a drain conduit 18.

r1`he crude oil or distillate entering the chamber 7 is preheated byvapors owing from the conduit 14 to the inner cylinder. In turn, theliquid in the preheating chamber 7 serves as means for condensing theheavier and undesirable fractions carried off by the vapors from thestill. This chamber, further, permits more constant and steady operationat variable atmospheric conditions, from which the inner cylinder isprotected by the body of the liquid in the preheating chamber. The largesurface presented by the baiiles within the inner cylinders facilitatesthe dissolving of the lighter hydrocarbons present in the liquid flowingthrough thev conduit 9 by the vapors flowing from the still, and alsothe recondensation of the objectionable parts present in the vapors,Awhich are, therefore, caused to return to the still with thenondissolved or vaporized fluid coming fromlthe overflow 9. i v

I claim:

1. A condenser comprising a pair of concentric oylinders forming anannular chamber, means for supplying iuid to the annu- 'lar chamber, anoverflowv from the annular the vapor inlet, said inner cylinder having avapor outlet. Y

2. A condenser comprising a pair of concentric cylinders forming anannular chamber, means for supplying liquid to the cham, ber, 'anoverflow conduit from the chamber to the inner cylinder, said innercylinder having a vapor` inlet and a 'vapor outlet, a series of spacedplates disposed between the overflow conduit and the vapor inlet, and aseries of spaced centrally-apertured plates alternating saidfirst-mentioned plates.

3.y A condenser comprising a pair of concentric cylinders adapted to bedisposed vertically and forming a vertical annular chamber, means forfeeding liquid to the annular chamber near the lower end thereof, an

overflow conduit from the upper end of the annular chamber into theinner cylinder, said inner cylinder having a vapor inlet near the lowerend thereof and a vapor outlet at the top thereof, a series of circularplates disposed concentrically with the inner cylinder and in spacedrelation with each other between the overflow conduit and the vaporinlet, and centrally-apertured 'an overflow conduit from the upper endof the annular chamber into the inner. cylinder, said inner cylinderhaving a vapor inlet at the lower end thereof and a vapor outlet at theupper end thereof, a spider within said cylinder near the lower endthereof, a rod mounted on said spiderconcentrically with the innercylinder, a plurality of circular Ylates carried by said rod in spacedrelation, a plurality of centrallyapertured plates carried by the innercylinder in alternation to the circular plates, and means for feedingliquid directly into the said inner cylinder.
